Patented July 9, 1912.

Original application filed May 4, 1908, Serial No. 430,647. Divided andthis application flied April 5,

. 1909. Serial No. 488,004.

To all whom it'mag concern: I Be it known that I, CnAnLEsH. TOMLIN- son,a citizen of the United States of ments in Uncouplin America, residingat Mansfield, in the county of Richland and State of Ohio, have inventedcertain new and useful Improve- Means, of which the following is a specication.

My invention relates to an uncoupling means which is especially adaptedto be used in conjunction with car couplers of the Janney type, and is adivision of an application filed byme on the 4th day of May, 1908,bearing Serial No. 430,647.

One of the objects of my invention is to provide an uncoupling meansthat can be operated from either side of the car and at an angle withthe couplers.

Another object of my invention is to construct uncoupling means wherebya central draw or pull is exerted on the locking device to impartmovement thereto to permit the knuckles to uncouple automatically and tobe yieldingly held in open position for coupling purposes.

Another feature of my invention consists in constructing the operatingmechanism so that in rounding curves or the like, the parts do not move,thereby obviating the wear incident to other uncoupling means, the partsof whichmove under like conditions.

I attain these and other objects by the mechanism illustrated in theaccompanying drawing, in which:

Figure 1 is a side elevation of a radial draft-rigging showing thedraw-bar and coupling device connected thereto and supported by a springdraw-bar carrier which permits additional vertical movement of thecouplers, if necessary; also a side view of the sheave-pulleys and cableor wire rope. Fig.

'2 is a plan view largely diagrammatic,

partly in section of the uncoupling means,

draw-bar coupling device, locking bar, the

spring draw-bar carrier and radial support. Fig. 3 is an enlarged planview of one looking "bar and bracket. 4 is a side elevation of Fig. 3.

In the drawings, 1 represents a part of the beam or support of the carbody, 2 a bracket which is secured to the car body having a slottedportion 3. The bracket 2 is provided with a hollow pivot pin 4 which isfitted to an aperture in the bracket. A pivot bolt 5 9 between thebottom of the pulley 7 and the face of the nut 7 The washers 8 and 9 arefor the purpose of keeping the wire rope or cable, which will bedescribed hereinafter, in the grooves ofthe sheave pulleys and preventit from moving from one sheave pulley to the other during the operationof the uncoupling means.

The draft rigging 10 is pivotally journaled on one end upon the pivotpin 4. The draw-bar 11 is secured to the end of the draft rigging by thebolts'12 and 13. Attention is called to the fact that the drawbar 11 isprovided with an oflset 14 adjacent to itsrear end leaving a space 15extending upward from the bottom. The free end of the draw-bar 11 isyieldingly supported by the spring draw-bar carrier 16 which is in turnsupported for lateral movement by the radial bar 17. The radial draw-bar17 is secured to the beam 1 of the car by bolts 18.

A bifurcated jaw 19 is threadably secured to the end of the locking bar20. Guide members 21 and 22 extend over the periphery of the sheavepulley and are fitted. to the jaw 19 to guide the wire rope or cable;said pulley being hereinafter designated 24. A pin 23 is fitted to thejaw 19 and the sheave pulley 24 is journaled thereon. Brackets orsupports 25 and 26 are secured to the car body by bolts 27 and 28. Theadjustable sliding handle bars 29 and 30 are supported by the brackets.Thebody portion 31 and 34 of the handle bars are provided with offsetsor shouldered portions 33 and 34. One end of the cable or wire rope 35is connected to the sliding handle bar 29 and the free end is made topass and travel over the sheave pulley 6; thence over the sheave pulley24; thence over the sheave pulley 7 and is connected to the slidinghandle bar 30. The eye bolts 36 and 37 form a connecting link betweenthe ends of the cable bars are connected to the sliding bar and whenmovementis imparted to the handle, the locking bar is moved rearwardlyunlocking the knuckle or moving the end of the locking bar back from theface of the coupler.

The movement of the sliding bars is inns, trated by the full and dottedlines 29, the

full lines showing the position of the locking bar when engagingthere'cesses (a) of are adapted to contact with the end of eitherbracket 25 or 26'to withdraw and hold the, inclined end b of slidinglocking bar 20,

from entering the recess .a of the opposing knuckle, but not allowin theknuckle of its own coupler to open. ,T e means of retaining the inclinedend b of the sliding locking bar 20 from the recess a of the opposingknuckle is necessary to uncouple the couplers. Also a great advantagewhen it is necessary tocouple the type of couplers as shown in thedrawings to a different type of coupler as it keeps the inclined end bof the sliding locking bar 20 behind the face or contour line of thecoupler.

The operation of my uncoupling means is as follows: When two cars arecoupled together through the medium of my improved couplers as s own inthe drawings, and it is desired to uncouple the cars, movement isimparted to one of the sliding handle bars that is connected to thelocking bar of one of the draw-headsthrough the medium of the cable 35or wire rope, the inclined, end Q2) of the locking bar iswithdrawn fromthe -bar in the path of thetail recess (a) of the opposed knuckle, anoperator then pulls the handle of one of the sliding bars on the othercar which bar is connected to the locking mechanism of a coupler asdescribed above, pulling the lock-bar backward against the tension ofthe spring (0) thereby compressing the spring until the inclined end(12) of the locking bar is forced back far enough to clear the tailpiece (d) of the knuckle. In order to cause the knuckles toautomatically return to uncoupled position, I provide a tubular memberor casin (a) into which a shoulder pin (f) is inserte leaving one endprojectin into the draw- I piece A coil-spring (g) is. inserted in thecasing leaving one end contacting with a pin (f) and is held in place bythe screw threaded plug (it) which compresses the coil spring (g) andthereby constantly exerts a pressure against the pin (f) to keep the endprojectinseam ing into the hollow portion of the draw-bar and in thepath and contacting with the tail piece of the knuckle so that when theknuces are released; from each other by the uncoupling means, they willbestarted to their proper positions for coupling purposes,

Having fully described by invention, what I claim and desire to secureby Letters Patent 1s:

1. In a device of the character described,

a radial coupler, a locking device therefor and releasin mechanism forsaid locking device including rotating means mounted on the pivot ofsaid coupler, a handle mounted .on said car'body and suitable meansconnecting said locking means, rotating means and said handle.

2. In a device of the character described, a radially -movable cou ler,a horizontal sliding latch therefor, said latch projecting in front offorward face of said coupler, releasing mechanism for said slidinglatch, includlng a handle, a bracket for saidhandle and cooperatingmeans on said handle and bracket whereby the said handle may be held inan intermediate position to retain said latch within saidcoupler. 3. Inan uncoupling means, the combination of a hollow draw-head, a pin topivotally support the draw-head, a locking bar movably mounted in saiddraw-head leaving one-extremity extending outside the drawhead, asheave-pulley secured to said extremity, sliding bars mounted on thebottom of the can-sheave pulleys journaled on said pin, a cableconnected to the sliding bars and looped around the sheave pulleyswhereby movement is imparted to the movable locking bars for uncouplingpurposes when the sliding bars are moved.

4. In a radial movable car coupler, the combination of a hollowdraw-head, a look.- ing bar movably mounted in said draw-head having oneof its extremities extending outside of thedraw-head, a bifurcated 'jawsecured to said extremities, a sheave pulley journaled in said jaw,sheave pulleys .journaled upon the pivot pin of a radial cou ler,brackets mounted on the car body, 'sli ing bars supported b saidbrackets, a cable connected to said siding bar and adapted to passaround said sheave pulleys and connect with the locking bar for acentralpull and impart movement thereto as and for the CHARLES H.
